  1. Thanks for your replies. I will try a multimeter and let you know how I go. Cheers
  2. Yes, I am now guessing that it is not giving me similar readings to the specifications because it is not in the water. I should have thought of that but I thought that the current draw would still vary out of the water with different speed settings (from 1 - 5) but it does not.....
  3. Hi jdp, thanks for your reply. Yes I followed the set up instructions very carefully and have re-synced a few times at 0 load to re-test. I am sure the wiring is correct too. It seems very strange that the monitor is reporting -1.9amps (or -23w) regardless of the speed setting of the motor. The specifications for the motor say about 7.5amps at speed 1 up to 35 amps at speed 5.
  4. Hi, I am new to these forums so my apologies if my terminology is not quite right. I purchased the BMV-700 battery monitor and I am having problems getting the monitor to show the correct amp usage and time remaining. I have been very careful to wire the shunt correctly such that the battery side of the shunt goes straight to the 12v battery negative and the loan side of the shunt receives everything from my negative bus I have mounted. I have an electric Watersnake 12v Boat Motor which is connected to the negative bus and therefore load side of the shunt and and the positive from the motor is going to a positive bus which is connected to the positive side of the 12v battery (with a 50amp circuit breaker). The small red positive cable of the BMV-700 goes to this positive bus as well. The problem is that the monitor is showing and amp draw of about minus 1.8-1.9 amps and minus 23w and is showing about 40 hours left from my 105 amp hour AGM battery. I know from the specifications that this motor draws between 7.5amps and 35amps depending on the motor speed setting (1-5). So the draw and time remaining are way off. At full speed (5) on the motor it should be showing about 35 amp draw and time remaining of about 1.5hrs (based on 50% discharge setting and 105ah battery). What am I doing wrong or do I have a defective unit? I only purchased the unit a few months ago and I have only just installed it. Someone's help would be greatly appreciated. Thanks
